VMS Help INITIALIZE, /QUEUE, Qualifiers, /PROCESSOR  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /PROCESSOR=filename
       /NOPROCESSOR

    Allows you to specify your own print symbiont for an output
    execution queue. You can use any valid file name as a parameter
    of the /PROCESSOR qualifier. The system supplies the device and
    directory name SYS$SYSTEM and the file type .EXE. If you use this
    qualifier for an output queue, it specifies that the symbiont
    image to be executed is SYS$SYSTEM:filename.EXE.

    By default, SYS$SYSTEM:PRTSMB.EXE is the symbiont image
    associated with an output execution queue.

    The /NOPROCESSOR qualifier cancels any previous setting
    established with the /PROCESSOR qualifier and causes
    SYS$SYSTEM:PRTSMB.EXE to be used.
